Geneva Double Curtain

The use of the Geneva Double Curtain in Vineyards

The branches are then turned at a 90 degree angle a couple of feet from the rootstock and supported by the wires. Each year, the canes are trained downwards.

Nelson Shaulis invented the Geneva Double Curtain system during the 1960s with non-Vitis vinifera grapes in mind, specifically the Concord varietal. It encourages higher yields than most other vine training methods and trellises. It also controls the canopy well and allows sufficient space to harvest mechanically.

Because Geneva Double Curtain trellises support up to 4 permanent branches, it is important that quality materials are used. The wires and posts must be sufficiently strong to support large vines. Weaker materials will likely need to be replaced and are more costly in the long run.

Geneva Double Curtain trellises are used to separate the vine’s canopy and thus increase sun exposure to grape bunches. The two sides of the vine are known as “curtains”, and the trunk is usually 3 to 5 feet high.
